Ok, this definitely helps in understanding how PDF works. However, I really do edit PDFs regularly and have no problems with the edited ones. Already mentioned it ITT, PDF-Xchange lets me do so many things that listing them would sound like an advertisement. Editing the existing text tends to mess it up, that’s true, but it’s not crucial for me and all sorts of other actions work almost perfectly.

You’re imagining some very ideal circumstances for working with PDFs that have nothing to do with my own needs, so I can’t really make use of your advice. :/
